P1258 Browse Basin Elevation

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. These line dataset from the Browse Basin Airborne Magnetic Survey, WA, 2013 (Offshore) survey were acquired in 2013 by the WA Government, and consisted of 190247 line-kilometres of data at 800m line spacing and 80m terrain clearance.
